Specification of Letters Patent.

Serial No. 86,083.

To all whom it may concern:

Be it known that I, SOLOMON M. CUTTER, a citizen of the United States, residing at Ashland, in the county of Middlesex and Commonwealth of Massachusetts, have invented an Improvement in Nailing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to nailing machines and particularly to nailing machines used in the manufacture of boots and shoes.

An object of the invention is to improve and simplify the construction of such machines, especially with respect to the arrangement and timing of the nail-delivering and nail-inserting mechanisms.

In the accompanying drawings,-Figure 1 is a side view of part of a nailing machine embodying my invention. Fig. 2 is a front elevation of the part of the machine shown in Fig. 1. Fig. 3 is a front view partially in section of the carrier for placing the nail in position to be driven. Fig. 4 is a detail showing the wire cutter and part of a lever for moving it. Fig. 5 is a horizontal section on line y, Fig. 6, through the wire feeding mechanism, said figure showing the wire cutter occupying a position parallel with the longitudinal axis of the carrier, and Fig. 6 is a vertical section parallel with the driver bar, and through the wire feeding mechanism, the line of section being transverse to the longitudinal axis of the carrier.

The head a of the machine erected on a suitable column a has suitable hearings to sustain the driving shaft a provided at one end with a cam a having operating parts a a and carrying a crank pin 0, The crank pin a carries a link 7) ointed at its lower end to a driver bar b free to be reciprocated in the head a, and provided with a driver 5 The part a of the cam a moves a lever b pivoted at 12* and employed to move a bar 6 carrying an awl b laterally in a direction to enable the awl forced into the stock to feed the stock in usual manner toward the driver and between a stock support 2 and a foot plate 3 of any one end to the lever 5 and at its other end to the frame, tends to maintain the roll 0 of the lever b in contact with the operating part a of the cam c A spring 0 attached to the awl bar and to the frame moves said bar away from the driver as the lower end ofthe lever is moved away from the driver.

The awl carrying bar If is pivoted to the free end of a lever c mounted on a shaft 0 said lever having an arm 0 provided with a roller stud c that enters a cam al at the rear side of the cam a, said groove actuating the lever c to reciprocate the awl bar positively in both directions, that the awl may penetrate the stock and be withdrawn therefrom after the operation of feeding the stock.

The parts so far described are substantially the same as described in United States Letters Patent N 0. 582,579, dated May 11, 1897.

The head has a pivot d for a lever d actuated by the operating part c of the cam a the lever reciprocating the wire cutter (1 to be described. The continuous wire 6 from which the nails are to be out, is sup lied by any suitable reel as A, and is led therefrom through a wire guide e where it is acted upon by a suitable Wire feeding mechanism shown as a toothed wheel 0 mounted on a shaft 6 provided at one end with a ratchet wheel 6 see Fig. 1, that is engaged and rotated intermittingly by a suitable pawl e at the end of a lever 0 provided at its upper end with screws e e the adjustment of which determines the extent of movement of the lever e, and consequently the distance that the wire is fed at each operation of the feeding device. The screw '6 engages the head a and limits the forward 10 entering a groove in the side thereof.

A spring 8 connected with lever 6 acts normally to hold the screw e against the inner end of the sliding pin. The wire is held pressed against the periphery of the feed sage wheel 6 by a roll f mounted on a stud f carried by a lever f pivoted at f and held yieldingly by. a spring f controlled by a screw f. The feed wheel moves the wire longitudinally so that its free end enters a passage in a nail carrier 9 represented as an enlarged circular block at one end of a rock shaft 9 having its bearing between a sup ort shown as two plates g g concaved and eld together bya suitable screw as g and presenting between them immediately above and below the carrier a driver passage g The shaft g has secured to it an arm g shown as provided with a cam groove g that is entered by a stud 12 see Fig. 3 on a movable throat piece 13 having a passage 14 to receive the nail acted. upon by the driver as the same leaves the carrier, said throat directing the nail while it is being driven into the stock, the cam groove causing the throat to be moved longitudinally to occupy a position to place its passage in the line of the driver when a nail is to be driven, and moving the throat away from the path of the driver when the awl is acting to feed the stock, the driver being then elevated. The arm g has a connected link y that is jointed to a lever g having a roller stud that enters a cam groove 9 in a block g fast on shaft (1?.

The wire cutter d is located in a space 15 between the inner plate 9 and the head of the machine, and it has a recess 16, see Figs. 4 and 5, at one side to receive the lower end of the lever d referred to, which is actuated by thepart a of the cam (L The cutter d is moved in a line parallel with the longitudinal axis of the shaft g, and meets the wire at right angles -to its longitudinal axis at a point close to the face of the carrier, and the wire is cut off in nail lengths and left in the carrier so that when a circular movement is given to the shaft g and carrier the nail is turned from a horizontal into a vertical position, and is put under the line of movement of the driver, and the plate g prevents the escape of the nail until it arrives opposite the pas- The head of the machine has connected with it by a screw 17 a stationary cutter 18, see Figs. 4 and 6, which in case the cutter (i fails to act, meets the wire as the carrier is moved circularly, and cuts off the wire leaving a nail in the carrier. This cutter also meets the wire substantially at right angles to its longitudinal axis, and if one cutter fails the other is sure to act and revent any breaking of the arts. The stationary cutter 18 is entirely inc ependent. of the movable cutter (i each performing its severing operation at different times and without the aid of the other. One means of securing this independence of action is by arranging the cutter 18 in such a position relative to the carrier 9 that its cutting edge is at all times 1.
